17.2
When the mode pins and the FWE pin are set in the reset state and a reset-start is executed, this
LSI enters an operating mode as shown in figure 17.2. In user mode, flash memory can be read but
not programmed or erased. The boot and user program modes are provided as modes to write and
erase the flash memory.
The differences between boot mode and user program mode are shown in table 17.1. Boot mode
and user program mode operations are shown in figures 17.3 and 17.4, respectively.
